To all 'whom t may concern.'

Be it known that I, GEORGE W. DYARMAN, a citizen of the United States,and a resident of New York city, in the county and State of New York,have invented certain new and useful Improvements in Ties for Railroadsand Road Constructions, of which the following is a specification.

This invention relates to a tie for railroads and road constructionswhich is made up of a plurality of wooden blocks, bound together in sucha manner that a tie of great strength is obtained.

In the accompanying drawing:

Figure 1 is a plan of part of a railroad track showing ties embodying myinvention;

Fig. 2 a section on line 2-2 Fig. 1 with the rails omitted;

Fig. 3, a similar section on line 3-3 Fig. 1, and

Fig. 4, a horizontal section of one of the blocks.

The main body of the tie is composed of a number of longitudinallyalined wooden blocks 1 which are connected with each other in a mannerhereinafter specified, and which should be of the same height and width,though they may differ in length.

At points set back from the ends of the tie body there extend at rightangles thereto, a pair of alined wings, each composed of one or moreblocks 2 which are flush with blocks 1, and constitute part of thestringers that support the rails 3. Blocks 1 as well as blocks 2, areprovided along each of their upright sides with a longitudinal groove,the grooves of adjoining blocks communicating with each other. 'Ihesegrooves are adapted for the reception of a number of metal binding rodswhich are preferably of semi-circular shape in cross section, the outerflat sides of the rods, being flush with the sides of the blocks. Two ofthese rods, designated asl, are U shaped and extend along the innersides of blocks 2 and along the sides of the blocks 1 intermediateblocks 2. Four of the rods, designated as 5 are L shaped and eX- tendalong the outer sides of blocks 2, and along the ends of blocks 1protruding beyond blocks 2. Opposite rods 4c and 5 are connected to eachother, by means of bolts 6, carrying nuts 7, and accommodated withinhorizontal bores of the blocks. In this way, all of the blocks 1 and 2constituting a tie are connected to each other in such a manner thatthey form a unit combining the cushioning properties of wood with therigid qualities of metal. If desired, the several blocks may befurnished with tongues 8 and grooves 9 at their meeting ends to increasetheir hold upon each other. S0 also, a pair of reinforcing bolts 10,carrying nuts 11, may extend longitudinally through the row of blocks 1above and below bolts 6 respectively.

It is preferred to alternate the double cross ties constructed asdescribed by straight or wingless ties, one of which is illustrated inFig 1. 'Ihis straight tie is composed of a series of longitudinallyalined wooden blocks 1, having grooved sides in which straight metalrods 12 are sunk, said rods being connected by bolts 13 passing throughthe blocks and carrying nuts 14. The straight ties are not only adaptedfor railroad construction but also for road construction, for whichpurpose two lines of said ties are set up along the sides of the road,while the space between said lines is filled in witha suitable road bedor pavement.

A tie constructed as described possesses numerous advantages:

It permits small wooden blocks and ends to be utilized for making up thetie, thus materially reducing the cost of the same. The tie can bereadily disassembled so that any one defective section may be replacedby a new section. Finally, as the tie body is Hush with the wings itwill, in conjunction therewith, constitute a Stringer or rail supportwhich owing to its peculiar shape is not liable to sink into `the soil.

I claim.
